Cobbs Creek Corridor Stormwater Management Plan


To improve a corridor of Cobbs Creek upstream from the existing Marshall Road restoration site, A.D. Marble and Company designed a site plan in 2005 for the Philadelphia Water Department.  The 12 project designs run along a 2-mile stretch of the creek and are sited in the vicinity of Cobbs Creek Park and Cobbs Creek Golf Club, including the confluence of Indian and Cobbs creeks. These stormwater best management practice designs are based on work completed by the Fairmount Park Commission’s National Lands Restoration and Environmental Education Program and the Philadelphia Water Department.

Design Section A

Upon implementation, these projects will serve to reduce streambank erosion and prevent contaminants from entering Cobbs Creek; constructed wetlands will treat pollutants, store runoff, and create habitat for wetland species. Click here for a list of native plants proposed for the site.
